STONEII-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 313.6%3, dated March 10, 1885..

Application filed August 14, 1884. (No model.)

To all whom it may concern:

Be it known that I, R. LESTER BARNEY, of ,Swanton, in the county of Franklin and State of Vermont, have invented a new and Improved StoneSawing Machine, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved machine for sawing marble or other stone,which machine is simple in construction, and is provided with devices for automatically feeding the required quantities of sand and water.

The invention consists in the combination, with a saw-frame, of a suitable base for supporting the stone, a tank for receiving sand and water, a bucket-chain for raising the sand and water, and a gutter for conducting sand and water that has been dumped into it from the bucket-chain to the block of stone being sawed. A tank'is also provided, from which a pipe extends downward, by means of which the sand remaining in the buckets is washed out.

The invention also consists in various parts and details, and combinations of the same, as will be fully described and set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

. Figure l is a side elevation of my improved stone-sawing machine, parts being shown in section. Fig. 2 is a side view of the bucket. Fig. 3 is a rear view of the same. Fig. etis a longitudinal sectional elevation of the base and inclined platform. Fig. 5 is a cross-sectional elevation of the same, on the line a: m, Fig. 4. Fig. 6 is a rear view of a bucket of different construction. Fig. 7 is a side view of the same. Fig. 8 is a longitudinal elevation of the faucet for drawing off the sand and water. Fig. 9 is an end view of the same.

The saw-frame A is hung in the usual mannor to reciprocate in the horizontal plane, and is connected with a pitman, B, for operating it. The block of stone, 0, to be sawed rests upon a suitable base, D, which in turn rests upon an inclined platform, D, on which a water-tube, E, is arranged, which isprovided with branch pipes E, for delivering jets of water upon the inclined platform,to wash the lsand, &c., down the same into a tank, F,

which is provided with a screen, F, to prevent pebbles or pieces of stone from being washed into the tank. The inclined platform D is also inclined downward from both sides to form a groove, D along the middle ofwhich groove the pipe E, provided with the spouts E, is located.

In the tank or box F a wheel, G, is arranged, over which a bucket-chain, H, passes, which also passes over a wheel, I, located above the wheel G.

A short distance below the upper wheel, I, one end of a gutter, J, is arranged, which extends down to a point over the block of stone 0, and conducts'the sand and water upon the inclined or swing boards K, from which they drop upon the block of stone. The mixture of sand and water is dumped from the buckets L of the bucket chain H into the trough or gutter J.

For the purpose of washing out all the par ticles of sand in the buckets, I have provided a pipe, M, which has its lower end bentto form a nozzle, M, adapted to deliver water into the buckets as they turn over the pulley or wheel I. The pipeM extends downward from a tank, N, on top of which a screen, 0, is arranged, which is provided at one end with an overflow, 0. Water is delivered by a pump through a pipe, I, upon the screen 0, passes through the same, through the pipe M, and through the nozzle M. Thescreen O prevents sawdust or any foreign substance that might be pumped up with the water, and that would clog the pipes, from passing into the tank N. All such foreign substances are carried over the screen by the force of the water and discharged from the nozzle or spout 0, whereby the screen is cleaned automatically, and can never be clogged. Each bucket L of the bucket-chain is provided at its upper end with a hook-lug, L, which is adapted to pass through a trans verse slot, I in the bottom of the next higher bucket, and thus, by hooking the buckets together, an endless bucket-chain is formed. The buckets are made of cast-iron, and their cavities must be so shaped that they can easily discharge the sand and water at the wheel I.

Instead of making the buckets in the manner described, they can be provided with jaws Z Z at the top and bottom, the bottom jaws be of the lower bucket, and through the tube a of the lower bucket, the buckets being thus united to form a chain. By having the buckets constructed in this manner the tube n and the bolt m can easily be replaced by others in case they are worn out.

My improved faucet (shown in Figs. 8 and 9)jconsists of a tube, S, having its open end curved downward.and provided with a laterally-projecting wing, S, to which a gate,"I,'

, having 'a suitable handle, is pivoted, In the bottom of the gate a notch, W, is formed. By having the bottom of the gate cut out in this manner all the sand, gravel, &c., in the faucet are'washed out every time the faucetis opened, even if it is opened but a very short distance.

The operation is as follows: A quantity of fresh sharp sand and water is placed in the 'tank F,and-raised from the same by means of the bucket-chain H to the gutter J, in one end of which it is deposited. It runs down the said gutterupo'n theinclined orswing boards K,and drops from the same upon the block of stone, thus coming in contact with the saws and do ing the sawing.- It then runs down the inclined platform D'back into the tank F. The tank F is provided with an overflow-pipe, F through which the waste sand and water flow off-that is, the sand that has lost allits cutting prope'rties and, being lighter, is held-in the water,

while the heavier sand settles. Inplace of providing the overflow-tank F- belo'w thebucket-chaimit can also be arranged at the upper end of the bucket-chain,as shown in dotted linesat R in Fig. 1. The sand and I water-are conducted from the said tank at or near its bottom through the gutter J to the inclined or swing boards K, and the waste 'sand and water overflow from the tank B through a suitable pipe or nozzle at or'near the top of the Said k. Fresh sand is tob o'f buckets whose relatively lower buckets are disposed in a return water and sand tank, said buckets discharging into a gutter with its lower 'dvv the sa -fram substantially as-and for the purpose-set forth. 5
